Astudent examines microscope slides containing different types of epithelial tissue. what is the most direct way to differentiate between types of epithelial tissue? a) epithelial tissue types may be identified by differences in dna. b) types of epithelial tissue are distinguished by different microscope staining techniques. c) different epithelial tissue may be identified by the presence or absence of a nucleus and other organelles. d) different types of epithelial tissue may be identified by the shape and overall structure of the cells that make up the tissue.

D) Different types of epithelial tissue may be identified by the shape and overall structure of the cells that make up the tissues.

Explanation:

Epithelial cells form a layer structure which covers most of the surfaces of the body. These cells perform variety of functions and exhibit different shapes, size and arrangement which makes up different tissues. For example columnar tissues (column like cells), cuboidal tissues (cube like cells) and others.

Hence, these epithelial tissues can be identified in a microscopic slide.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
